Job Roles
Management - There are many sectors in the film industry, for each sector there must be a manager who keeps control of what the people in that sector are doing. For example at the BBC there is a editorial manager who will see the content of the material before it is published and discuss with the editorial if anything needs to be changed. As well as this, management can also involve being in charge of transport, catering crew, managing locations and many other jobs depending on the production. The pay, responsibilities and qualifications also depend on the type of management for example a sales and marketing manager will be expected to work with a team to develop and implement sales and marketing strategy. The salary for this can be from £24,000 to £32,000 depending on the employer.
Creative - These roles help bring a film or program to life. People in these sectors can be art directors who visualise a scene and help make it. The film director is part of this since they create the general tone of the fim. The music composers, script writers, actors, costume designers est. are all part of this. Together they create the film/program. This can only happen however under managers who control all of the people in these different sections. If someone took a job as director of music in this area than they would be expected to support the work of composers and music directors with production teams so that all the musical performances can be implemented into the production. Experience is heavily required in a job like this. The salary for this can be from £34,450 per year.
Editorial - In the chain of management within a company such as the BBC, the editorial prepares material for publishing, being sure to check that the material isn't bias or insulting to the audience. The editorial must be prepared to interact with the content producer or manager as sometimes there may be debate on whether or not the content should be released which may be due to controversial content est. Editorials usually have assistants who help the chief editorial in all stages of publication with books, magazines est. Editorials are required to have social, economic or business studies and need to show enthusiasm, self motivation, language skills and the ability to stay calm under pressure. Starting salaries for editorial assistant are likely to be in the range of £15,000 to £23,000 however it varies depending on the size of the company and type of employer. 
Technical - People working in the technical section of film and TV are responsible for making sure all of the equipment on the set is working as well as placing the equipment in the position that the director wants them in. This means that if the director wants to create a certain look with the lighting then it will be the moving light operators job to put the lights in place relevant to the camera as well as making sure the settings on the lights are correct. As well as the light operator there are also other jobs in the technical section such as production sound mixer, boom operator, sound designer and music editor as well as camera operator etc. Camera operators often have competitive salaries meaning the pay will depend on the companies competitors. 
Research - This must be done in post production so that the company can be sure that the production has the best chance of being successful. This is done by researching into how popular productions similar to your own where as well a what audiences think of your production plans. This is done through quantitative and qualitative data, jobs that do this include TV researcher, research assistant, on air planner, head of research etc. The marketing and sales manager can also be part of this section as they usually have to research other products in order to sell their own.

People are needed to in these jobs to calculate how much money the company can put into the production as well as how much money can be borrowed from different sources and where that money is going to go into the production. It is also involved after production and goes into advertising and distributing. Jobs in finance included production accounting, distributor and sales agent. Management accounting involve producing monthly forecasting of where the money in the company is coming from and what it's going towards, jobs like these often require experience with high analytical skills. The salary can be from £38,000 to £45,000 however once again this depends on the experience of the employee. 
Organisational - Jobs dealing with organisation need people with high management skills.

They also have to insure deadlines for things such as re-filming are met so the production can run smoothly and to plan. Jobs like this involve transport manager, location manager, casting director and assistant etc. Casting directors have to have good communication skills as well as having knowledge of cinema and actors.

This can be done by giving clear objectives that people under the admin should work to. Jobs that do this include accounts, casting, health and safety, locations, transport and catering. Managing accounts in part of this section.Working Patterns
